Smiles warmly to you! First of all, congrats and kudos to you! To have survived and to be still fighting is nothing to sneeze at as you well know yourself. Second of all, welcome back indeed!
I would highly recommend Life & Death. Also Businesses and Hobbies! But the most important thing is to just enjoy playing your game again when you feel up to doing so. And when you don't, you can plot what you WILL do when you can do so again...Mwhaahaahaha! *LOL*
And yes, have a very Happy Birthday, too!
(Edited to add: Oh! How could I have forgotten!?! As someone else said, you should certainly pick up Growing Together and Horse Ranch too! Nods muchly You will love both I'm sure!)
